Transport of Anthropogenic Pollution and Boreal Forest Fire Emissions to the Arctic during Summer 2008
Aircraft measurements taken as part of POLARCAT campaign (the Polar Study using Aircraft, Remote Sensing, Surface Measurements and Models, of Climate, Chemistry, Aerosols, and Transport) in the Arctic were aimed at investigating pollution transport and atmospheric chemistry. Anthropogenic pollution...

Aircraft measurements taken as part of POLARCAT campaign (the Polar Study using Aircraft, Remote Sensing, Surface Measurements and Models, of Climate, Chemistry, Aerosols, and Transport) in the Arctic were aimed at investigating pollution transport and atmospheric chemistry. Anthropogenic pollution and boreal forest fire emissions followed by subsequent transport to the Arctic were measured in summer 2008. We combine aircraft measurements with simulations using the WRF-Chem model (Weather Research and Forecasting Model including aerosol and chemistry) to investigate cases of pollution transport to the Arctic during summer 2008. Two case studies are investigated in this work. The dynamics for transport of fire plumes originating over Canada that as well as anthropogenic pollution plumes primarily from the north east US will be presented to gain insight into the origin and fate of pollution transported to the Arctic. We also investigate the transport and evolution of anthropogenic pollution from East Asia. Model results are compared with high-resolution aircraft data obtained during POLARCAT in order to investigate the critical processes responsible for horizontal and vertical transport.
